Great Filter and Great Price
Only filters I use. I’ve got a Street Glide and a Night Train and both have the trusted K&N brand filters. The built in nut on the filter makes it super easy to add and remove.

Nut on Top is easy to round out.
I like the quality of the filter itself. I purchased this filter specifically because of the nut on top that would make it easy to remove from my Street Bob. When I went to remove it however it very quickly rounded out and I had to use a strap wrench to get the filter off the regular way. The shape of the nut is strange. It gets larger towards the bottom so it's not a real solid fit for a socket. Some people have no issue with it but I did not get any benefit from it at all.

Top Quality Filters ! The nut is for removal ONLY !
I have been using K&N filters for my motorcycles for over 40 years. They have never let me down. Pro Tip: the 17mm nut on the filter is for REMOVAL ONLY ! Do not use the nut to tighten the filter. If I can't get it tight enough by hand I use a strap wrench on my Harley to tighten the filter.

Good Filtration And Never Had An Issue
Long time user of K&N filters and yet to have any issue. I go through 4-6 filters a year and they have been consistent throughout the years. The addition of the bolt head has made removing the filter a lot easier since on my Road Glide it's tucked back in there a ways (unless you over-tightened it last filter change!).I feel they have always been a good value and one I trust.
